Personally, I didn't find anything wrong with the GPS on mine (AT&T Captivate). You didn't say which version of the Galaxy you have (Captivate, Fascinate, etc.), but I know that before Froyo even, AT&T did push a separate update to their customers which supposedly was to fix the GPS (I don't know if it did though, since as I said I wasn't having issues before the update).

The latest update on the Samsung Vibrant (JI6) fixed GPS issues for 2.1. A similar update has been pushed to all the variants, as far as I know. As you can tell from the other responses, GPS issues aren't universal and even for those having trouble it wasn't always completely broken. It is safe to say it is fixed now, though -- and I see no reason to think it would be broken again in 2.2.

As an update, the official Froyo release started rolling out to unbranded Galaxy S devices in the UK on the 4th of November. Carrier branded devices (and the rest of the world) are expected to be released over the next few weeks.

No, I upgraded to the unofficial FROYO (Android 2.2) for Samsung Captivate and the GPS sucks. The signal does not lock and when it does, after waiting for days and sucking up the battery, it loses the signal just as fast. I am so frustrated with the GPS problem that I am thinking about switching carriers to get a different brand phone - like HTC or Motorola.

I also upgraded my Samsung Galaxy S to Froyo 2.2 and lost my GPS lock that I had on 2.1 which sometimes worked. I tried to a factory reset and cleaned everything on my phone and after the reset comepleted I had to input information and the first thing I tried was GPS and still could not get a lock. I download GPS locator before and that also did not lock onto a GPS. I will try what "user1100" said and see if that helps.

Bottom line Froyo 2.2 has GPS lock issues.. maps and navigation works without a GPS lock..:(

Well I also have problems GPS lock issue on my Galaxy 5 i5500, hope this can fix your phone. I got tips to fix this issue.
Remember to write down the default setting before change the GPS setting below, in case you want to go back.

I am writing to inform you that this link is very helpful to fix GPS problems coming with samsung galaxy s froyo. But please be aware that this may have a risk (less probably) but worked very fine with me.

There was definitely a problem with the GPS on my Samsung Captivate I purchased from AT&T a week after it launched, but I wouldn't classify it as unusable. It would take several minutes sometimes to first fix even when outdoors, but it would stay fixed as long as nothing obstructed it, such as my car ceiling. If it had a fix recently, it would be quicker at getting a fix as well. I used GPS Status to keep the GPS Almanac up to date which helped a bit, and applied several fixes people had suggested with minor improvements. Even official updates from Samsung had little improvement. I finally decided to replace my ROM with a third party and my GPS was greatly improved unlike anything Samsung had provided before. Generally, any third-party ROM using the JK4 modem like Paragon
